On July 17, 2015 at Firefly Con, a game featuring Luo Tianyi, YANHE, and Yuezheng Ling was announced to be in production and would be developed by Aquatrax. It was later revealed that it was called "Zion" and it would feature two different playing styles.[2] Later in the year, Aquatrax built a Facebook page and a Twitter account for Zion and continued to announce their progress through these social medias. The developers intended to release the game in China during the first week of October.[3]

In September, Aquatrax announced that they would distribute Zion as a free download in the App Store and Google Play if the Facebook page received 10,000 likes before the official launch. They were also offering more than 10 free tracks. However, this goal was not accomplished.[4]

When the game released for iOS products, Aquatrax occasionally released themes and other goods for free.[5] The Android version was originally due release in December 2015, but was delayed due to slow development progression. In January 2016, it was revealed that it was delayed even further due to China's firewall restrictions and in compensation for the wait, Aquatrax hinted that another character would become available in the game.[6]

In February 2016, MAYU was hinted to be available in the game and was later confirmed in April.[7][8]

In March 2016, the Android version was confirmed to be releasing in April and was later announced to be released on April 29th.[9]

In April 2016, Dots Mode was introduced. In addition, Aquatrax offered free prizes if people "attended" the pre-registration event. These included in-game coins, songs, characters, and menu themes.

The game is played using the touchscreen and is available in three modes: Pure Mode, Dual Mode, and Dots Mode.

Dual Mode is played by using the buttons located on the four corners of the screen. The ones at the top are red, while the ones at the bottom are blue. The player must tap on the buttons that correspond with the colored orbs appearing on the screen.

Pure Mode is played by tapping on the orbs that appear in order on the screen.

Dots Mode was introduced prior a few weeks before the Android release and is played by tapping on the buttons that ripple in order on the screen.[10] The ripple must be in line with the button to receive full points. In addition, buttons with two red dots must be held in place until the dots connect and the player must release when they do.
